LARGE Birds of prey- We're talking Eagles and Ospreys.

I've been doing some preventative research, and well, it seems the large birds of prey are what really are brave here. We had an Osprey attack and kill a Creambar cockerel just feet away.

I know these birids, and the other large raptors we have here (I know for certain there's a few eagles nesting nearby, I see them just over the interstate from us constantly taking off from the same patch of tall trees) are protected, and I wouldn't *dare* injure a vital part of our wetlands eco-system.

However, I do want to prevent losses, so I would love to hear what deterrents you guys have used that have worked to really prevent these larger preds from even being tempted (we do have roofed coops/runs being built, but in the mean-time, we'd love to be able to graze our birds. (We have Large Fowl, and turkeys)

My Grandma has the same problem. You could try sitting out with them, supervising. Or, if you need to calm down from the day, watch them ever so peacefully.
Yes, covered coop and run Is great. Also, do you have a dog? If so, you could possibly train it to stand watch on and off. Our dog is a Great Pyrenees and German Shep. mix, she makes sure that not one sparrow lands in the pen with the hens. We have a hawk lingering around.....She have keen eye to make sure that the hawk esp. stays away!
